SUSPENSION DEVICE FOR LAMPS,

PECIEICl-TTEQII forming part of Letters Patent No. 332,695, datedDecember 22, 1885.

Application tiled July ll, 18S-i. Serial No. 137,456. (No model.)

T0 all whom it may concern:

Be it known that I, VILLLiM H. Bancooii, a citizen of the UnitedSta-tes, residing at Vashington, in the District of Columbia, haveinvented new and useful Improvements in Suspension-Lamps, of which thefollowing is a specification.

This invention relates to the lixtures,77 so called, ofsuspension-lamps, and more particularly to the devices immediatelyemployed for supporting the iounts of such lamps.

The object of this invention is to provide a satisfactory harp orsubstitute for the harp, which willallow the lamp and chimney to beintroduced without tilting, and secured without danger of dislodgm ent,besides very greatly reducing the weight and size of the lixture, anddoing away wit-h that part of the harp or lamp-support which ordinarilyendangers the heads of those using it or passing near.

Vith this object in view my invention consists, chiefly, in aninclosing-ring ier a lampfount, in combination with the arms of alampharp,whereby said ring is suspended from the xture, one side of saidring being movable to allow the lateral insertion and removal of thelamp-forint.

The said invention Afurther consists in certain details ot' constructionand combination, which will be hereinafter fully set forth, and moreparticularly pointed out in the claims.

In the accompanyingdrawings, Figure 1 represents an elevation ot' anextension-lamp embodying my invention, the shade and shadering beingpartly broken away to show more fully one of the supporting rods or armsofthe lamp-harp. Fig. 2 represents a detail View ofthe lamp, its shade,and proximate devices, the shade and shade-rings being in verticalsection, and iiat bars or castings being used in the construction of thelamp-harp instead of rods. Fig. 3 represents an enlarged detailperspective view of the lamp-inclosing ring and the lower parts of thelamp-harp arms shown in Fig. Fig. 4 represents an enlarged detailperspective view of the interlocking ends ofthe lanip-inclosing ringshown in Figs. Zand 3. Fig. 5 represents an enlarged detail perspectiveview ot' the hinge and ad- Fig. 6 represents an enlarged detailperspective view ofthe hinge and adjacent parts of the ring shown inFig.

l, and shown also in Fig. 8 on a larger scale and more plainly. Fig. 7represents a similar view of the interlocking hook and eye of thislamp-inelosing ring. Fig. 8 represents an enlarged perspective detailview of this lampinclosing ring.

The same letters indicate the same or corresponding parts in therespective figures.

A designates the canopy of an extensionlamp iixture, and A an eyewhereby it is suspended from a hook fixed in the ceiling of anapartment, as usual. In this canopy are pulleys a, indicated in dot-tedlines in Fig. l, over which are passed the chains B, having the annularconnterbalance-weightC attached to their outer ends, and the uppershade-ring or crown-ring, D, attached to their inner ends.

There is nothing novel in the above devices or their combination orarrangement. They are introduced merely because some form ofsuspension-fixture is requisite, or at least desirable, to fullyillustrate the application of my invention. To this upper sliade-ring orcrown-ring,D,the shade Eis secured by means of screws e, which take intoits neck or in any other convenient manner. There may be, as shown inFig. 2, a lower or base ring, F, in additiomwhich receives the loweredge of said shade, or this base-ring may be dispensed with, as in Fig.l.

Gdesignates alamp-fonnt, which is provided with an annular groove, g, inits periphery, and preferably near its top 5 and H and I designate,respectively, the burner and the chimney belonging to said fount.

In all these parts also I claim no novelty, they being well known and inconstant use, as Shown.

J designates two lamp -harp arms, which extend downward from thecrownring D, their upper ends being passed through openings in saidcrown-ring and screw-threaded to receive nuts j, above said ring,wherebythey are held in position. Instead of these screwthreaded ends andlnutsthe upper ends of said lamp-harp arms may be provided with hooks forcatching into or through said crown-ring, or with any other similarmeans of attachment, such as are now in use for fastening harps toshade-rings.

K designates a lamp-inclosing ring, which fits into the groove g, so asto prevent the IOO fount G from risingr or descending through said ring.This ring consists of a relatively' iixed section, K, and a hingedsection, K2, the two being connected at one end by a pintle, 7c, whichallows the ring-section K2 to be turned, so as to open the side of thelamp-inclosing ring and allow the fountto be inserted without raising itabove said ring.

The fixed ring-section K ot' the latter may be in one piece with thelamp-harp arms J, as shown in Fig. or it may be simply attached thereto,as shown in Figs. 2 and 3; but in either case it is suspended by saidlamp-harp arms, and when in use is practically immovable with respectthereto. y

As clearly shown in Fig. 8, the lamp-harp arms J and section-ring K maybe formed of a single rod or length of strong wire bent upon itself toform a semicircular horizontal piece between the lower ends of the twoparallel suspension-rods or lamp-harp arms, eyesjj being formed on theouter side of the angle made by each arm J with said semicircularring-section K. The other ring-section, K2, is of similar material, andprovided at one end with an eye, 7c', and at the other with a hook, k2.

Vhen the parts are put together foruse, the eyes j and k are arrangedparallel to one another, and the pintle k is passed through them andheaded at each end, as indicated in Fig. 6. The hook k2 is then passedthrough the eye j and further secured there by a nut, 7c3, which turnson the screw-threaded tip of said hook.

Instead of being formed from a cylindrical rod or wire, the lamp-harparms J and ring K may consist of cast-metal or of wrought-metal bars orplates or sheet-metal strips having the required form. In this case, asshown in Fig. 4, the detachable ends ot' the lamp-inclosingring-sections are provided-with interlocking hooks M M', leaving all thefaces flush, athumb-screw, N, being passed down through the hook M ofring-section K2 into the hook M of ring-section K; or a screw may extendup from the lower hook through the upper and receive a thumb-nut aboveit.

Either the screw or the hooks may be dispensed with, but it ispreferable to employ both.

As shown in Fig. 5, the other ends of said ring-sections are also madeflush and hinged together in any ordinary way consistent therewith. Thering-section K is provided with ears O, Figs. 2, 3, 4, and 5, which areperforated to allow the passage of the diminished lower ends ot'lamp-harp arms or bars J, said diminished ends being screw-threadedbelow said ears to receive nuts P, which, with the shoulders o on saidarms, immediately above ears O, hold said ring-section K steadily inplace.

Ot' course said lamp-harp arms and ringsections K may be cast in onepiece, or when the rod or wire or sheet-metal form of lampharp isemployed the arms may be separate pieces fastened to said ring-sectionin any convenient manner.

The lamp harp is essentially the same, whether made of cast metal orwire, or in two, three, or four pieces. The lamp-harp arms andlamp-inclosing ring constitute the whole ofit in either case, anddispense with by far the greater part ofthe weight ofthe ordinary harp,andconsequently of the counter-balance also. The iixture is thus madevery light to handle and convenient for packing, and there is a verygreat saving of material. There is no protruding part of the lamp-harpbelow the fount or around the lower part thereof, and many accidentswill thereby be avoided. Finally, to introduce a lighted lamp` with thechimney on requires no further preparation than the unfastening ofring-section K2 and turning it back on its hinge. The lamp is theneasily passed in laterally, and the ringseotion K2 is turned intogrooveg and fastened to the ring-section Kagain. Of course t-hering-sections K K2 and the other devices named may be used with alamp-fount which does not have a groove, g, but is of sufcient diameterat the top not to pass through the ring. It will not be held sosecurely, however.

The screw O or nut k3 should be attached to ring-section K by a chain,Q, as shown in Figs. 4 and 7, in order that it may be ready when wanted.

Vhen a base-ring for the shade is used, as in Fig. 2, the arms R, forsupporting it, may be cast with the lamp-harp arms J, or otherwise maderigid therewith.

Thelamp-harp arms J, if of wrought metal, may be attached toring-section K by heading them below the same, or any other permanentattachment may be adopted instead of the detachable nuts beforedescribed.

Having thus described my invention, what I claim as new, and desire t'osecure by Letters Patent, is-- l.
